plumbing fixtures and more particularly to effect their connection tothe usual soil pipe outlets opening through the walls or partitions of buildings for the purpose, in a manner to eliminate the usual and expensive joint wiping operation.

A further object of the invention is to provide for a joint of the character mentioned and one which will effect marked saving in time, labor and material in the installation of the same, in comparison to that now required in the heretofore known types of such joints, in a manner to not in any way lower the usual efliciency of such installations.

With the foregoing and other objects and advantages in view, the invention resides in certain new and useful constructions and arrangements of parts as will be hereinafter more fully described, set forth in the appended claims and illustrated in the accompanying drawings, in which .Y v

Figure 1 is a vertical section through an outer wall of a building and showing an embodiment of the invention in its position of use, the latter, together with certain of its associated parts being shown in section,

Figure 2 is a view similar to that of Fig. l, butshowing the use of the joint or union in connection with an arrangement of the plumbing installation within a vpartition Wall of a building, and

Figure 3 is an enlarged sectional detail of the joint and certain of its associated parts 0f a plumbing installation. j

Referring to the drawing-wherein similar characters of reference designate corresponding parts throughout the several views thereof, a indicates a usual form of soil dis-l charge pipe as positioned within a Wall of a building for the connection therewith of a soil tail pipe b, leading from a soil trap c, of

a wash basin or other similar plumbing fix- 'within the bore of the enlarged '2, "a -f'errule 3, `ferrule 3 is intended to'strengthen this part ture d, all of conventional form and disposed 1n their usual operative relation one withre- `spect toftheother. To admit of the connectionof the soil discharge pipe a and the trap `tail pipel b, ina desiredmanner, a'union l I is normally employedand is passed through an opening in one side of the Wall of a building for the purpose.

Inf carrying out the objects and purposes of the invention, the union-1 is of a suitable length of tubing, of a ductile metal such. as

lead, and is spread to a larger diameter, asat 2, "at its end to be engaged within the open end of the soil discharge pipe a, tov receive endportion preferably of cast iron. This of the union -against being distorted from its normal shape when a packing 4, preferably of oakum is forced into position within the open end ofthe soil discharge pipe a, and within the enlarged engaged end"2 ofthe union. To assure of the packing lilbeing retained in a leak preventing state, a packing ring 5 is inserted into the open end of the soil discharge pipe ci and around the union body 1, after the packing 4 has been previously placed in'position.

A second ferrule 6, of metal and prefer- 'ably of brass, is inserted in the bore of the union l, at, the end of the same opposite to the enlarged end portion 2and is retained in position therein `with a portion of its length projecting Voutwardly Vtherefrom. This projectingportion of the fel-rule@ isl threaded as at 7, 'to receive thereonfa slip 'nut 8, the latter being positioned on thetail pipe b prior toits engagement through the ferrule 6 with the union l, for Vthe purpose.

To prevent leakage from around theferiule v J'- 6 and the'slip nut 8, apacking, which'may be inthe form of a rubber gasket l9 'is-housed? vwithin the slipl nut 8 andv is Vproperly compressed betvveen vthe same and the opposed end of the ferrule 6 when the slip nut is tightenedinplace. ,y l,

In use', when a plumbing system is installed withinV a vbuilding theunion will be placed inposition in the; wallsatfallpoints whereever the-usual .plumbingAiXtures,r such v,as the wash basin (l, are to be installed and with their enlarged end portions 2 connected to the soil discharge pipe rz, as heretofore er;- plained. Non', when the fixtures are to be connected up to the unions l, all that the workmen are required to do is to place the slip nuts S with the packing or gasket 9 housed within their threaded ends, on the tail pipes b, of the soil trap c and insert the free ends of the tail pipes into the unions l through the ferrnle (i tor a proper or required distance when the slip nuts 8 maybe engaged with the threaded ends of the ferrule 6 and tightened thereon.

In Fig. 2 of the drawing, the union 'l is shown as having the end portion opposite to the enlarged end portion angular-ly bent to admit of its installation within the thinner partition walls ot a building, but the union is otherwise in every respect similar to that form ot the union as hereinbetore described.

In both instances, in the seating of the ferrules 3 and (i Within their respective ends of a union l, the saine are to be sweated into proper and prominent position therein in the Well known manner of metal sweating operations. It should he noted that the bore of the errule 6 is of a slightly smaller diameter than that of the union l, so that the inserted end of the tail pipe b, of the trap c, is maintained free from all possible Contact with the Wall of the bore of the union, and this is particularly desirable for the purpose of facilitating the installation of the tail pipe b Without effort or interference, such might occur should the inserted end of the latter scrape along or bite into the relatively sott metal `forming the Wall ot the union.

lVithont further description it is thought that the features and advantages ot the invention Will be rcadilv apparent to those skilled in the art, and it will ot course be understood that changes in the torni, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention or its scope as claimed.

Having thus tally described the invention what is claimed is 1. A soil trap slip joint wall' outlet connection comprising a union et ay dnctile metal, a lerrnle set in the adjacent end of said union and havinga portion projecting therefrom, said terrule having its bore of a less diameter than that of the hore of said union and its projecting end exteriorly screw threaded, a packing nut engaged on the threaded end otl said terrnle, and a wall cap enclosing said packing nut and the exposed end of said union.

2. A soil trap slip joint Wall outlet connection comprising a union of a ductile metal, a terrule set in the adjacent end of said union and having` a portion projecting therel'roni, said terrnle having an exterior diameter greater than that of the bore of said union and its interior diameter less than that of the latter, said ferrule also having its projecting portion exterior-ly screw threaded, a packing nut engaged on the threaded end of said terrule, and a wall cap enclosing said packing` nut to the exposed end of said union.
